tlontinuation in part of application Serial No. 720,510, filed September 16, 1912. This application filed August18,191t. Seria1'1tfo.857,'3t9.

To all whom it may concern: I

Be it known that l Lnwrs T. WILCOX,- a citizen of the United States, and a resident of Peekskill, in the county of Westchester, fitateof New York, have invented certain new and useful Improvements in ,Wick-Raising Devices for Oil-Burners, of which the following is a specification.

The improvements relate to oil burners,

and particularly to burners adaptedto burn liquid hydro-carbon through the medium of a wick, and the objects, among others, are to provide a device for raising and lowering the wick, to regulate the flame, which will be of simple, inexpensive, and at the same time durable construction, and convenient andefi'eotive in operation.

So far as the improvements described and I shown herein correspond with my application, Serial No. 720,510, filed September 16, 1912, particularly improvements shown in Figures 13 to 16 inclusive of that application, it is my desire and intention to have the applicationregarded as a continuation and division of said application No. 720,510. The present improvements, however, are in some important particulars an advance over the structure shown and described in the said earlier application, and may also in some particulars be regarded as a carrying forward of the constructive deas therein set forth.

The improvements are illustrated in the ac'ompanying drawings, in which- Fig. 1 is a side elevation of a wick oper ating device embodying the improvements. Fig. *2 is a horizontal section of the same on the line 2.2 of Fig. 1 looking in the direction indicated by the arrows in that fig-- ure. Fig. 3 is a vertical cross-section on the line 3-3 of Fig. 1 looking in the direction indicated by the arrows in that figure. Fig. 4 is a'view of one of thespur wheels which engage the wick, and its connections, taken on the line H of Fig. 2 and looking in the direction indicated by the arrows.

The wheel A by which the device is operated is keyed on the end of the shaft B, which rotates in the sleeve F. Fixed to this shaft a short distance from the wheel A is a disk C, provided with a series of perforations 0' near its periphery, and a pointer D, loosely mounted on the said shaft, and

provided with a pin D adapted to enter the perforations, which is pressed against the disk by a spring N strung on the shaft and held under compression between the said pointer and the wheel A. The purpose of the spring is to hold the pointer D in its normal position with the pin D in one of the holes 0, so that it can only rotate with the disk and shaft, and when checked will also check the rotation of these parts. The

pointer has an outer portion D connected with the body portion by a step or bevel,

and this portion has an arrow point D in a punched out aperture adapted to register with the markings E of the dial E to indicate the position of the wick and the resulting height of the flame.

The dialE is fixed on the end of the sleeve- 1*, and is, therefore, stationary. It has a stop E composed of a piece of its metal stamped up, and a check E similarly formedg but capable of being depressed to.

,the level'of the face of the dial so as to permit the pointer to pass it and come in contact with the stop 1E. The dial also bears in connection with its markings words indicating the condition of the flame and giving instructions for setting the device.

As will be seen by these instructions the wick is first turned until it is level with the upper edge of the wick tube, and the pointer arm is then drawn back from the disk C, thus removing the pin 1) from the peripheral recesses C, an'df-moved until it registers with the dial. marking indicating the high flame.- These markings are visible through the aperture above the point D llt is then released and allowed to be pressed into engagement with the disk by die spring N. Before the wick is lighted 1t should be turned up until it projects above the wick tube. The wheel is therefore turned clockwise past the check E and until it comes in contact with the stop E. The wick may then be lighted easily, and turned down to high or low flame, as desired. When it is desired to extinguish the flame the wheel is turned counter clockwise until the pointer comes in contact with the lower edge of the stop E. This is a very useful and safety insuring arrangement, for the reason that it is not necessary for the operator to see the stop E, but merely to turn the wheel tion of the rear wall.

until it is checked by the stop. As burners of this character are frequently operated in dimly lighted places or before or after daylight, and very little illumination is provided by the blue flame, it is important to provide means for lighting,regulating and extinguishing the burner -which do not require visual observation in connection with their operation. The check E? will indicate to the operator when the flame is too high, and thus prevent the unusual volume of flame which results when the wick is turned above the upper edge of the wick tube while the burner parts are heated. At the same time when it is desired to start the burner it is a very simple matter to press the'check E down with the finger of one'hand while turning the wheel with the other hand, or to force the pointer to slide overv the said check. By this provision the danger of producing a very high, smoky and dangerous flame by accident, as well as the danger of leaving the wick high enough to produce vapor and continue. the combustion without the knowledge of the operator is avoided.

The sleeve F has the end'opposite the dial E secured in the housing G of the spur wheels, and the shaft B extends beyond the lend of the sleeve to the rear of said housing, having its end opposite the boss G of said housingformed by stamping up a seethe shaft within the housing is. rectangular in cross section, and the wheels H are passed over this portion and held against rotation by the angular form of their central apertures. They are separated by the collar J on the said shaft and held in position by the collar K, which extends beyond the end of the shaft and around the boss Gr so as to formwith the said boss a bearing for the rotation of the shaft and parts fixed thereon.

In constructing and assembling the wheels H and the adjacent parts, the wheels H and collars J and K are passed over the square end of the shaft and soldered thereon so as to form with said shaft a. practically integral structure. The shaft is then passed through the opening of the housing G which is surrounded by the punched-in flange G 1 and the end of the collar K placed over the boss G The sleeve F is next passed over the shaft and through the said aperture of the housing until it meets the first wheel, and then soldered in the said opening from the outside of the housing. The dial E may then be fixed to the outer end of the sleeve and the perforated disk C and wheel A fixed on the outer end of the shaft, with the spring N strung on the shaft and the pointer arm D loosely mounted on said shaft between them. The structure is now complete 1 and ready to be applied to the wick tube by The portion B of soldering the flanges aroundthe open side of the housing thereto and applying a suitable brace 0r bracket, if desired, or by any other satisfactory method.

The-wheels H pass through the outer shell of the wick tube L and engage the wick M in the usual manner, the said wick being provided with the ordinary perforated metal reinforcement O at this point.

In moving the pointer D a leverage is member and means for automatically causing the same to connect the said pointer with the said member at different points, whereby the former may be secured thereto in different positions, and a dial fixed with respect "to the said pointer for indicating the position of the wick.
